Answer 1

This is a sample code to word-wrap texts with D3:

var nodes = [
    {title: "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut"}
]

var w = 960, h = 800;

var svg = d3.select("body").append("svg")
    .attr("width", w)
    .attr("height", h);

var vSeparation = 13, textX=200, textY=100, maxLength=20

var textHolder = svg.selectAll("text")
    .data(nodes)
    .enter().append("text")
    .attr("x",textX)
    .attr("y",textY)
    .attr("text-anchor", "middle")
    .each(function (d) {
        var lines = wordwrap(d.title, maxLength)

        for (var i = 0; i < lines.length; i++) {
            d3.select(this).append("tspan").attr("dy",vSeparation).attr("x",textX).text(lines[i])
        }
    });


function wordwrap(text, max) {
    var regex = new RegExp(".{0,"+max+"}(?:\\s|$)","g");
    var lines = []

    var line
    while ((line = regex.exec(text))!="") {
        lines.push(line);
    } 

    return lines
}
